DITCHING AND GRADING'PLOW.

SPECIFICATION forming part Of Letters Patent N0. 258,064, dated May 16,1882.

' Application filed January 14, 1882. (No model.)

To all whom 'it may concern:

Be it known that we, FRANK A. HILL, of Benicia, in the county of Solanoand State of California, and MosEsJ. CHURCH, of Fresno, in the county ofFresno and State of California, have invented a new and usefulImprovement in Ditching and Grading Plows and we hereby declare that thefollowing is a full, clear, and exact description of the same.

Our invention relates to plows; and it consists mainly in the improvedand novel construction and adjustment of the extension of themold-board, and in other details of construction hereinaftermore fullyset forth.

Figure is a side elevation, and Fig. 2 a plarf view, of the improvedapparatus.

In these drawings the plow is reprcsen ted as mounted upon an axle, thebeam of the plow being connected thereto, as shown in Fig. 1. The axleis provided with cranks m w, and is unusually heavy. The wheels areprovided with wide tires and with adjustable boxes H, which are boltedto the hub with three small bolts, and can readily be replaced when wornout or broken. The plow is of the slip-share class, and its depth isadjusted by means of the lever D, which is fixed, as shown more clearlyin Fig. 1, to the rock-shaft V. This is mounted on suitable standards,and is provided at its ends with arms P P',Fig.2, which are connected tothe crank-axles by means of links P P. The lever engages with a bentrack-bar, 1, by means of which it is held in any required position. Tothe beam, which is of the ordinary bent form, a permanent mold-board andlandside are connected and securely braced. A movable or adjustableextension of the mold-board is shown at A. This is pivoted at the lowerforward corner, as shown at R, and is held at the forward upper cornerto the fixed mold-board by means of a bolt passing through a slot. Thisconstruction permits the movable mold-board to be raised to an angle offorty-five degrees, more or less, as may be required, to enable theoperatorto adjust the machine to suit the soil in which he is working.The ditching mold-board is supported upon a lever, K, which is pivotedat 0?, Fig.2, and is capable of swinging laterally on this point. .It issupported on a bar, U, Fig.2, around which it moves toaccommodate itselfto the different positions of the end of the movable mold-board A. Thecross-bar is supported on suitable standards. The rear end of the leverK is provided with a lever, I, engaging with a rack-bar, J, on the leverKand supporting by means of a chain the end of the detachablemold-board. This mold-board is also adjustable laterally, the anglewhich it makes with the landside being variable at will by means of thejointed bars 00, Fig. 2. These bars are connected to the mold-board andlandside by means of suitable hooks and eyes or in any other convenientway, and may be increased or decreased in length, as required.

The landside is also composed of aiixed and removable part, L L, thelatter being bolted to the former by means of bolts E E, and. whendesired this part L may be removed with its appurtenances and with theditching mold: board, and the plow used as a deep tiller.

In order to carry the landside when theplow is not working, we haveprovided a casterwheel, W, upon the end of a pivoted bent lever, S. Thelever is pivoted at the end of the landside, and when the machine is notat work the lever is thrown forward into the position shown in Fig. 1,which brings the wheel under the end of the broadside, thereby slightlyelevating it. When it is desirable to lower the landsidefor work thelever is thrown backward to trail upon the ground.

The pole T is fixed adjustably to the front cross-bar, t, of the frameand to the axle. Preferably it is clamped to the axle by a strap andbolted to the front bar by two or more bolts. This front bar is providedwith a series of holes, so that the pole can be shifted laterally, andalways be located in the centralline of draft in whatever position ormanner the plow or mold-board is adjusted.

The plow-beam, frame-work, and all other appurtenances are preferablymade of metal, except the pole and sustaining-lever K, which may bewood. The whole machine is constructed with a view to strength as wellas for the special functions, and may be attached to a number of horseswithout danger of breakage in any of its parts.

Having thus described our invention, what we claim is- 1. In aditching-plow, the combination of the carrying-wheels, the rook-shaft V,the plow names to this specification in the presence of having apermanent mold-board, the pivoted two subscribing witnesses.

extension A', having independent vertical and lateral adjustment, andthe lever K, pivoted 5 to the rock-shaft and connected to the extensionof the mold-board.

2. The combination, with the mold-board, of the extension A, pivoted atR, and having the pin and slot G, the support K, and the rack and 10lever J I.

In testimony whereof we have signed our FRANK A. HILL. MOSES J. CHURCH.
